1 Overview1.1 Positioning

In scenarios involving plazas, blocks, roads, and highways with a poor mains supply or nomains supply, supplying power becomes an issue. As a solution to this problem, Huawei hasdeveloped the PowerCube 500, which includes small-power solar equipment and light

emitting diode (LED) street lamps. The PowerCube 500 is an ideal choice for locations withabundant solar energy but without reliable mains because it is environment friendly, easy toinstall and maintain, theft-proof, and highly reliable.

There are three types of PowerCube 500:

Solar video surveillance power supply solution

Solar wireless local area network (WLAN) power supply solution

Solar street lamp power supply solutionThe PowerCube 500 consists of an energy plant system (EPS), integrated controller and

converter (ICC), and energy storage system (ESS).

Figure 3-6 Network diagram for the solar video surveillance power supply solution(single-controller scenario)

Figure 3-7 Network diagram for the solar video surveillance power supply solution(double-controller scenario)

The solar video surveillance power supply solution works in the following way:

In strong sunlight, PV modules convert solar energy into currents, which then convergeat the solar controller. The solar controller monitors the power supply. The PV modulessupply power to video surveillance devices and store surplus energy in the ESS.

In weak sunlight, PV modules cannot generate sufficient electric energy. Both the PV

modules and the ESS supply power to video surveillance devices.

Figure 3-16 150 Ah gel ESU

A gel ESU is designed for an ESS and used in solar power supply solutions. It has thefollowing features:


23/41

PowerCube 500




17

Its electrolyte does not dry even if the gel ESU is overcharged or is stored or operating at

a high temperature. A gel ESU is insusceptible to thermal runaway because of its largeheat capacity and good heat dissipation. A gel ESU has the electrolyte mixed with silicadust to form an immobilized gel, which makes the electrolyte immune to leaks anddelamination.

Its cover is elegantly designed and made of acrylonitrile butadiene styrene (ABS) thathas high corrosion resistance and strength. The cover is reliably hot-melted, eliminatingthe potential for leaks.

Its separator has high porosity and low resistance, which provides a large space forstoring electrolyte.

Its terminals are made of lead based poles with copper cores, ensuring high current bearing capacity and corrosion resistance. The poles are double sealed to prevent leaks.

Its safety valve opens and closes under an appropriate pressure to prevent gel ESU bulges.

The technical specifications for a gel ESU are as follows:

The gel ESU voltage is 12 V, and the capacity is 65 Ah, 100 Ah, 150 Ah, or 200 Ah.

A gel ESU can be charged and discharged 500 times at 35°C if the depth of discharge(DOD) is 30%.

A gel ESU has a float lifespan of more than 8 years at 25°C (77°F).

A WLAN consists of the following components:

Wireless AP

A wireless AP is a gateway for a wireless network and has similar functions as a hub in awired network.

Wireless antenna

A wireless antenna enhances sent and received signals. It is used when two networkdevices are too far away from each other to communicate due to signal degrading andtransmission rate decreasing.

For details about a WLAN, see the Huawei WLAN AP Quick Reference Manual.

5 Solar Street Lamp Power Supply Solution5.1 Solution Configuration

The solar street lamp power supply solution uses LED street lamps with one or twocantilevers. The two cantilevers for a street lamp can be at the same height or at differentheights. The solution mainly applies to single-lane roads, two-lane roads, and car lane +

sidewalk.

The solar street lamp power supply solution consists of PV modules, a solar controller, an

ESS, one or two LED street lamps, and a pole.

5.2 Network Diagram and WorkingFigure 5-4 shows the network for the solar street lamp power supply solution.

Figure 5-4 Network diagram for the solar street lamp power supply solution

In strong sunlight, PV modules convert solar energy into currents, which then converge at thesolar controller. During the day with good sunshine, the solar controller charges the ESS. Onovercast days or at night, the ESS supplies power to LED street lamps.

5.3 Components

5.3.1 PV Modules

The PV module voltage is 18 V or 36 V. If two or more PV modules are used, connect the PVmodules in series or parallel depending on the load voltage before connecting them to the

solar controller.

If the load voltage is 24 V and two or more 18 V, 100 W PV modules are used, connectthe PV modules in series.

If the load voltage is 24 V and two or more 36 V, 100 W PV modules are used, connectthe PV modules in parallel.

Only components with the same specifications can be connected in series or parallel.Connecting components with different specifications in series or parallel will damage the

components.

Figure 5-5 shows two types of PV modules.

Figure 5-5 PV modules

5.3.2 LED Street Lamp

An LED street lamp is supplied with DC power. It has the following features:

Its shell structure is made of high-strength and lightweight aluminum alloy materials andtherefore is safe and reliable, providing a protection level of IP65. The shell surface isanodized or sprayed with protective paint to resist corrosion and extreme weather. All

shell materials comply with the restriction of the use of certain hazardous substances(RoHS) directive.

The innovative cantilever rotational structure allows the lamp to rotate between – 30degrees to 90 degrees to adjust the illumination angle.

The power cable connector can be quickly inserted and removed, ensuring ease ofmaintenance.

The patented modular structure facilitates maintenance.

5.3.3 ESU

During the day, the solar controller charges ESUs by converting solar energy received byPV modules into chemical energy. At night, the ESUs convert the chemical energy intoelectrical energy to power loads.

Gel valve-regulated lead-acid (VRLA) ESUs are most widely used in a solar energy

system because the ESUs are easy to transport, have no liquid inside and no leakage, andhave a long lifespan.

The ESU performance varies according to temperature. The ESU operating temperatureranges from – 10ºC to +50ºC (14ºF to 122ºF). You are advised to install ESUs under theground to prevent theft and to extend the ESU lifespan as the underground temperaturevaries slightly.

Do not short-circuit ESUs in use because electric sparks caused by short circuits mayinjure personnel. Protect ESU cable connectors when connecting or disconnecting cables.

For example, wrap the cable connectors by using electrical adhesive tape. Lead-acid ESUs contain lead and lead compounds. To prevent lead pollution, do not

uncover ESUs unless required and do not damage the protective layers for ESUs. If theESU lifespan ends, request local ESU recycling professionals to collect, transport, anddispose of waste ESUs.

5.3.4 Solar Controller

The solar controller monitors and controls the status of the solar street lamp power supplysolution, protects ESUs by various means, and switches on or off solar street lamps based on

configurations.

Figure 5-8 shows a solar controller.

Figure 5-8 Solar controller

The solar controller has the following features:

Solid, durable, compact, and corrosion-proof aluminum shell

Printed circuit board (PCB) filled with epoxy to prevent dust and water at a protectionlevel of IP68

Compact structure and small size Easy to configure by using an infrared remote management

Scheduled on/off switching of intelligent street lamps

Advanced programming functions

External temperature sensor, which provides automatic temperature compensation
